The expansion of ground-fault circuit-interrupter (GFCI) protection in the 2020 National Electrical Code® (NEC®) is a step toward increasing electrical safety regarding electric shock protection.
What is fault current? What is short-circuit current? The answer is the same for both questions, because they are two different ways of saying the same thing.
Our role as inspectors plays a vital role in assuring that homeowners and the public are safe from electrical hazards. Being an informed inspector by knowing what the NEC says and why changes occur is critical to your continued role in this process.
Although changes to the 2020 National Electrical Code for PV systems have been covered in previous issues, this article compares the 2017 requirements with the 2020 requirements and determines how clarifications have been made.
The NEC is revised every three years and the code adoption process begins anew. Here is a comprehensive overview of electrical code adoption in the US in 2020.
Electric shock drowning (ESD) tragically occurs when a child or adult enters a body of water that is electrically energized or when the water around a person suddenly becomes energized.
The 2020 edition of the NEC addresses many of the electric shock hazard concerns addressed by the 2017 edition and subsequent Tentative Interim Amendments (TIA)s concerning electric-shock drowning (ESD).
Kitchen islands have been getting bigger and bigger for years. How big does the island need to be to require more than one receptacle outlet to be installed? The 2020 NEC requirements answer that question.
The CPSC estimates that 50% of home electrocutions have been prevented by the introduction of Ground-Fault Circuit Interrupters (GFCIs).
Let's discuss the importance of GFCI technology, how to properly install a GFCI circuit breaker, and the expansion of GFCI requirements per the 2020 NEC.
